It's probably best if it's something that you've run across in your daily life and found the need for personally. It probably just won't be interesting or would be confusing otherwise since, if obscure enough, the data returned may be easy to mess up. Think back to stuff you've done recently. For example, recently I needed to do some wildcard searching and pattern matching on a list of last names for a writing project. This turned out to be much more of a pain in the ass than I'd thought to even get a hold of the right dataset. More of a SQL thing than a REST thing, but you get the idea.
